The Noctar System is an Intermediate-Mass Black Hole (IMBH) based cosmological setting of the Earth of INEFFABLE.
I - CENTER: Black Hole
Type: Intermediate-Mass Black Hole (IMBH).
Mass: 50,000 Solar Masses.
Event Horizon Diameter: Approximately 150,000 km (close to Jupiter's diameter).
Accretion Disk: A massive plasma ring extending millions of km outside the event horizon, emitting purple/ultraviolet light and heat due to friction. It is the planet's main energy source.
II - PLANET: Earth
Orbital Distance: 30 Billion km (200 AU) away from the black hole.
- Note: This distance is safe; the tidal effect does not tear the planet apart, and the radiation is not fatal.
Orbital Speed: 15 km/s (flows through space at half the speed of Earth).
A Year (Full Orbit): Approximately 13 Earth Years. (This is why the public uses the concept of "year" for 1 and 13, the calendar is based on "Cycles" and "Seasons").
Rotation (Day): 24 Hours.
Axial Tilt: 15 Degrees (Creates slight
seasonal differences).
Diameter: 30,000 km. Internal structure: Low cavernous / porous.
Gravity: 1.0 g.
Atmosphere: 1.5 ATM Pressure (Thick). Nitrogen, Oxygen, and a high concentration of Greenhouse Gases (to trap heat).
A - EARTHS SURFACE:
Diameter: 30.000 km
The surface area (A) of a sphere (a planet) is calculated using the formula:
A = 4πr²
Since the radius (r) is half the diameter (D):
r = D÷2 = 30.000÷2 = 15.000 km.
A = 4 × π × (15.000)² ≈ 2.827.433.388 km².
(÷)
The Earth in Reality = 510.000.000 km²
(≈) 5.5
The surface of Earth in INEFFABLE = 5.5x larger than the earth in reality.
B - EARTHS DIVISIONS
The world is physically separated into distinct zones.
B - I. The Living Area (Main Inhabited Zone)
Structure: This area is not attached to the main world mass, but is a kind of huge, flying island (a section that has risen up from the world). 1/5 of the surface.
Boundaries: It is surrounded by massive mountains, and the area where it lifted off is also characterized by huge mountains.
Horizontal Layers: The Living Area itself is composed of two flat, horizontal surfaces:
First Horizon: The upper, main surface.
Second Horizon: The lower surface, which is also flat. Its Lighting Source: The Second Horizon receives its light from the planet's core.
B - II. Outerlands
Proportion: Constitutes 4/5 of the surface.
Role: This vast area is where the mythological erastake place.
B - III. Third Horizon
Structure: A ribbon-like cloudy area located above the world.
Inhabitants: This is where the powerful beings known as The Ethereal and the Ethera (Lords of the Third Horizon) live.
B - IV. Innerlands
Internal Structure: The planet's core and interior feature caverns and porous areas.
Role: The Innerlands are the underground caves/caverns used to maintain the necessary gravitational pull, fixing the surface gravity at 1.0 g despite the planet's 30,000 km diameter.
III - SOLAR STARS (Two)
Type:
- Evvel: F-Type Yellow/White Giant.
- Ahir: K-Type Orange Giant.
Location: They orbit the black hole much farther away from the planet (approx. 50 Billion km).
Appearance: When viewed from the planet, they do not heat it, they just look like two very bright "eyes." They provide the planet's "Daytime" light.
IV - SATELLITE SYSTEM (Heat Balance)
Five moons orbiting the planet determine the short-term weather.
LUX (Stove Moon): Covered with warm crystals. Emits infrared heat.
TITAN (Hammer Moon): The most massive. Pulls LUX, heating its interior.
AERO: Gaseous outer surface.
Moon: two normal moons in total.
_________________
SEASONS (Not based on Orbit, but on the "Disk")
Since the planet orbits the black hole very slowly, there are no classic Summer/Winter seasons. Seasons are determined by the Black Hole's "Feeding" + the status of the sun's light:
Bright Season (Summer - Lasts 3 months): The black hole devours intense matter. The accretion disk glows, purple and green lights increase, and the planet warms up (Avg. 28°C). Auroras are intense.
Dim Season (Winter - Lasts 3 months): The black hole's feeding decreases. The disk dims. The planet cools down (Avg. 10°C). The moon LUX helps with warming.
__________
A very strong magnetic field is needed for black hole radiation and auroras.
Large core + fast rotation + Titan tide –> logical explanation.

Art of the Atmosphere
The atmospheric lighting is determined by two main factors: the activity of the UV Accretion Disk and the two distant stars (Evvel and Ahir).
Bright Season (Summer):
Daytime: The sky color is Purple-Turquoise. This is due to the intense UV light from the actively feeding Black Hole Disk plus the starlight.
Nighttime: The sky is Deep Violet / Indigo (with intense Auroras). The stars are not visible, but the Disk still glows.
Dim Season (Winter):
Daytime: The sky changes based on the stars' position.
Midday: The color is Dark Blue / Azure. The starlight is scattered by the thick atmosphere.
Sunset/Sunrise: The color is Orange/Reddish-Yellow. The light travels farther through the atmosphere, scattering the blue light.
Nighttime: The sky is Gray-Black. Both the Disk and the Stars are providing minimal effective light.
When The Moons Appear
The planet has a total of five moons: LUX (Stove Moon), TITAN (Hammer Moon), AERO, and two normal moons. Since the user states that the sky sometimes shows two moons, the appearance can be described as follows:
1. The Dominant Moons (LUX and TITAN)
Their appearances are vital to the world's stability and season/weather.
LUX (Stove Moon): As the moon covered in hot crystals that emits infrared heat, it is likely visible frequently (especially during the cold Dim Season) and may have a constant reddish glow.
TITAN (Hammer Moon): As the most massive moon, its appearance is often visible, likely in a phase similar to a large, dominant celestial body.
They appear simultaneously ("two moons are visible") when their individual orbital positions bring them above the horizon and outside the planet's shadow at the same time.
2. The Less Visible Moons
The two normal moons and AERO (gaseous surface) are either smaller or less reflective, making them harder to spot frequently. They only become noticeable when their orbits align perfectly with the viewing conditions.
3. Starry Night Sky
The sky is described as covered in stars when the two main stars (Evvel and Ahir) are not providing light. This usually occurs during the nighttime of both seasons, but is particularly noticeable in the Dim Season Night when the UV Disk is also dark.
